Product introduction
Color-coated aluminum coils are the surface coating and coloring treatment of aluminum plates or aluminum coils. The commonly coated aluminum coils are fluorocarbon color-coated aluminum coils and polyester color-coated aluminum coils. They are widely used for Veneer, aluminum honeycomb panels, aluminum ceilings, roof surfaces, leftover material, cans, and electronic products. The performance of the color-coated aluminium coil is very stable, and not easy to corrode. Besides, the surface layer of the color-coated aluminum coil can achieve 50 years of quality assurance after special treatment. The weight of them per unit volume is the lightest among metal materials. Color-coated aluminum coils are currently the most popular new material.

Application
Coated aluminum coil and sheet are more resistant to keep food fresh. Coated aluminum coil and sheet improves anticorrosive properties of aluminum, which are commonly used in food packaging, containers and cans. In addition, the application of coated aluminum coil and sheet embraces large industries including composite panel, ceiling, door, windows and electric appliances.
Color Chart
Color Match
1. For custom' color requests, we can deal as following:
A. Supply a physical sample of custom color. A color sample on metal is preferred. If other, it is also acceptable. But the color matching rate may be not good as color on metal.
B. New color sample is usually offered by our paint supplier in 5-7 days, special color should be in 7-10 days.
C. Upon receipt of color sample, please approve in writing as soon as possible. Once you approved, we will arrange purchasing and production.
Note: Color difference maybe occurred in different production batch, so it is suggested all panels are placed in one order for same project. And keep same direction as arrow on protective film when installing to avoid any color difference by vision.
2.For general colors, please refer to our color chart
Packing
Plastic film wrapped inside and carton packing. Wooden pallet with steel strip tied. Buyers can slao choose to pay for wooden case packing, which enables safer and more room saving in loading.
